ful Improvements in Canning Apparatus, of

which the following is a specification.

This invention relates to canning apparatus.

lvloreparticularly, it relates to apparatus for puttlng up and preserving fruits, vegetables or provisions in tin, glass or other cans.

The ob ects of the invention are to provide very simplle apparatus, suitable for use at home wit out a factory equipment for thus preserving such articles.

To this end the invention comprises a boiler, certain trays for holding cans during the process, means for adjusting the same in positionwithin -the boiler, and means for' andling the same, as more fully pointed out hereinafter, reference being had to the accompanying drawings, in which- Flgure 1 represents a plan view of the app aratus, showing cans and crates in place;

ig. 2 -re resents a side elevation of. the same, wit part of the boiler broken away, showing the water level, the section being taken at the 1place indicated by 2, 2 in Fig. 1 and Fig. 3 s ows one of the crates and the device for managing the same, viewed in side elevation.

The drawings show one form of apparatus embodying the invention,

. boiler in. the manner well known. The

boiler has parallel sides 7, 7, the tops of steps or horizontal surfaces 9, arranged at graduated distances from the level 7 of the. They may be maintained in boiler side. place in any suitable manner. The: method shown in the drawings consists of two straps 10 which arefastened to each side of each support and pro ect downward, loosely embracing the boiler wall outside and inside,

thus preventing the support 8 from movingoit of it sidewise, and, nevertheless, permitting said support to be adjusted to any desired position cndwise thereon. If preferred, any other desired form of fastening might be used.-

he apparatus also comprises three crates or hanging trays adapted to hold cans in which the fruit or other products are to be packed. These trays are preferably all alike and consist of a framework of band iron, as shown in the drawings, in which one band 11 passes longitudinally under the center of the tray and. rises vertically at each end to a certain level 12, where it is bent sharply outward as shown clearly in Fig. 3, forming hook-handles adapted to engage and rest upon the side walls of. the boiler., Crossbands 13 are arranged upon it to form the bottom of the crate, and are bent upward at the'sides and there fastened to a band 14 passing around the top of the tray considerably below the level 12. This crate or tray is intended to be immersed in water, and the open work structure provii'lcs free access for the Water to the cans 18 which it holds; and by reason of the hooks 12 the bottom is sure ported horizontally to hold the cans at fixed distance below the top of the boiler. By this feature of the invention a-tray is provided which is supported from above with handles easily accessible for moving the same, and which, nevertheless, has no rods or bars crossing the top of the tray to interfore with the placing and removal of cans. It is also a feature of the invention that, if desired, these hook-handles may project outward far enough over the sides of the boiler to remain somewhat cool, and thus be handled with impunity, without the aid of any lifting appliance. It is, however, preferred to use a lifting pole 15, having handles 16 at each end, and equipped with hooks '17 spaced at proper distances for engaging the rookhandles 12 of the trays. By this each crate The hooks 12 are also adapted to rest upon the steps? of the supportS, as shown for the crate A in Fig. 2. When so resting the level of the crate is raised within the boiler. The water line is arranged so that the level of the top of the trill come between the posi- I the cans are supposed to have tron ooonpieo o the tops oi tile cons, ween previo been closed, except for a. small tee crate is in ts-lo'aves vent 9.

by booking the pole lioolzs under the handles 12 on the erste and lifting the some into position A, setting the crate l on snoli one of the steps 9 as tne level oi eons ust soove boiling. This causes the can to expand and. and gases to beexhausted from t v through the vent hole.
